Application filed February 28, 1921. Serial No. $8,306.

T aZZ whom it may concern.

Be it known that T, HENRY K. AUSTIN, a citizen of the United States,residing at Reading, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in SolderingTools, of which the following is a. specification.

This invention relates to a soldering tool comprising a copper bit and ashank to which the bit is secured, the shank being provided with ahandle.

The object of the invention is to enable the bit to be revolublymountedon the shank, so that it may be turned to many ditterent positions, andstand at many different angles relatively to the shank, and may be:tolded beside the shank to reduce the length, of the tool and enable itto be conveniently stored when not in use.

The invention is embodied in the improve ments which I will now proceedto describe and claim.

Of the accompanying drawings forming a part ot'this specification,

Figure 1 isa perspective view of my improved t-ool.

Figure 2 is a side view, parts being shown in section.

Figure 3 is a fragmentary side view, the bit being shown in section online 33 of Figure 2.

Figure i IS a section on line ib-4 01. Figure 1. 1

Figures 5 and 6 are side views, showing a chisel-shaped bit, a portionof the shank being broken away.

Figure 7 is a section on line 7-7 01 ure 5.

Figures 8 and 9 are end. views of the tool shown by Figures 5 and 6.

Figure 8 is a view similar to Figure 7.

The same reference characters indicate the same parts in all of thefigures.

In the drawings, 12 represents a shank, and 13 an arm at one end of theshank, said arm and shank being formed by bending a cylindrical metalrod near one of its ends. in the arm is formed a peripheral groove 1t.15 represents an elongated copper bit, having in its inner end portion asocket 16 formed to fit the arm 13. The bit is revoluble on the armthrough a complete circle, and is provided with a set screw 17, adaptedto engage the groove 1%, and lock the bit in any angular position towhich it may be revolved. The bit may, therefore, be moved to and lockedin the position shown by full lines, to elongate the tool to its maximumlength, or in the lowest dotted line position shown by Figure 2, toreduce the tool to a minimum length for storage in a tool box. The bitmay also be moved to various intermediate positions, as the nature 01":the work performed may require, some of these positions being shown bydotted lines in Figure 2. i

The acting end of the bit may be pyramidal, as shown by Figures 1, 2 and3, or may be chisel-shaped, and provided with a thin edge 18, as shownby Figures 5, 6, 8 and 9.

When the tool is formed as last described, it is preferably providedwith an additional arm-receiving socket l6, intersecting the socket 16.In this case the groove lt and set screw 17 are arranged as shown byFigures 7, 8 and 9, the set screw being engageable with the groove tohold the edge 18 either at right angles wit-h the arm 13, as shown byFigures 5, 6, and 8, or parallel with said arm, as shown by Figure 9.The operator is therefore enabled to adjust the edge 18 to suitdifferent requirements of the work in hand.

The shank 12 may be provided with a screw thread 20 at its outer endportion, and with a fixed collar 21 at the inner end or the screwthread.

i Vith the rod may be engaged an outer wooden handle section, internallythreaded to engage a portion of the thread 20. Between the section 22and and the collar 21 may be interposed and clamped an inner handlesect-ion 23, which is a sleeve molded from. asbestos fiber, renderedsuitably plastie and solidified by drying after being molded.

T claim:

1. A soldering tool comprising a cylindrical rod, bent near one end toform a shank, and an arm, the latter having a pcripheral groove, anelongated bit having an arm-receiving socket in its inner end portionand revoluble through a complete circle on the arm, the bit beingprovided. with a set screw adapted to engage said groove and lock thebit to the arm at any point to which the bit may be revolved, so thatthe bit may be locked in a position parallel with the. shank, andprojecting either outward or inward from the arm, either to elongate itsouter end and provided with two intersecting arm-receiving sockets, andwith a set screw adapted to engage said groove and lock the bit to thearm with the chisel point either parallel with the arm, or at rightangles thereto.

In testimony whereof I have a flixed my signature.

HENRY K.v AUSTIN.
